0008 FindTaglib
0009 ----------
0010
0011 Try to find the Taglib library.
0012
0013 This will define the following variables:
0014
0015 ``Taglib_FOUND``
0016       True if the system has the taglib library of at least the minimum
0017       version specified by the version parameter to find_package()
0018 ``Taglib_INCLUDE_DIRS``
0019       The taglib include dirs for use with target_include_directories
0020 ``Taglib_LIBRARIES``
0021       The taglib libraries for use with target_link_libraries()
0022 ``Taglib_VERSION``
0023       The version of taglib that was found
0024
0025 If ``Taglib_FOUND`` is TRUE, it will also define the following imported
0026 target:
0027
0028 ``Taglib::Taglib``
0029       The Taglib library
0030
0031 Since 5.72.0
